Description

  The present invention relates to a plastic bottle handle attached to a plastic bottle in which a handle attachment portion is formed, and a bottle with a handle to which the bottle handle is attached. In particular, the present invention relates to a bottle handle that can be firmly attached to the handle attachment portion of the bottle.

  A large plastic bottle or the like for storing cooking oil is heavy, and a handle is attached to the outer peripheral surface of the trunk so that it can be easily carried. As a method of attaching the handle, there is a retrofitting method in which a bottle having a shape with a handle mounting recess is formed on a peripheral surface by biaxial stretch blow molding, and then a separately molded handle is attached to the handle mounting recess. Are known.

A bottle to which a handle is attached by this method is disclosed in Patent Documents 1 and 2 below. The grips disclosed in these patent documents extend from the grip part long in the bottle vertical direction, the arm part protruding from the end of the bottle vertical direction, and the upper arm part toward the lower arm part. And a fixed plate (support plate). In either handle, the upper and lower arms are forcibly fitted into the handle mounting recess formed on the bottle side, and then the fixing plate (support plate) is forcibly pushed. It is made to engage with the front-end | tip part of a part. When the fixed plate (support plate) is engaged with the lower arm, the lower arm is prevented from bending upward and the distance between the upper and lower arms is kept constant, so the handle is attached to the handle.

Japanese Patent No. 3508897 Utility Model Registration No. 2568990

  The conventional handle has a lower arm portion as a thin plate, and is easily bent in the vertical direction. Then, this is forcibly bent downward by a fixing plate (support plate) integrally formed with the upper arm portion and pressed against the lower end surface of the bottle-side handle mounting recess. Accordingly, the space between the upper and lower arm portions can be maintained in a widened state, so that the protrusion formed on the upper and lower arm portions fits into the groove on the bottle side, and a state where the handle is fixed to the bottle is formed. In the bottle with a handle having this configuration, the grip fixing strength cannot be sufficiently increased unless the shape accuracy and rigidity of the handle mounting portion formed at the same time as blow molding are secured.

  Here, when the bottle is blow-molded, the preform is gradually stretched and blown from the mouth side in the blow mold. Since the lower end surface of the handle attachment portion is curved on the side opposite to the stretch blow direction, it is difficult to form the portion in close contact with the molding surface of the blow mold. In addition, the lower end surface portion is formed by being pressed against the blow mold forming surface in the final stage of stretch blow, so that the stretch ratio is higher than other portions, so it becomes thin and the rigidity in the out-of-plane direction is reduced. It tends to decrease.

  For this reason, in the bottle manufactured by biaxial stretch blow molding, it is difficult to ensure the shape accuracy and rigidity of the lower end face of the handle attachment portion. The lower arm of the handle attachment portion is in contact with the lower arm portion of the handle, and a protrusion formed on the arm portion is fitted therein. Therefore, if the shape accuracy and rigidity of the lower end surface of the handle attachment portion cannot be ensured, the lower arm portion of the handle is likely to come off from the lower end surface.

  As described above, in the conventional handle, the lower arm portion has a shape that is easily bent up and down. And the handle is fixed to the bottle by this lower arm part which is easy to bend abuts and fits into the lower end surface of the handle attachment part with low shape accuracy and insufficient rigidity. For this reason, in the case of a large bottle or the like, the lower end surface of the bottle handle attaching portion is not able to withstand the applied load and deforms, and the handle is easily detached from the lower arm portion.

  In the conventional bottle with a handle, this point is not taken into consideration at all, and there is a problem to be solved that the fixing strength of the handle is not sufficient.

  In view of these points, the problem of the present invention is that the grip mounting portion formed on the blow-molded bottle has poor molding accuracy, and even if the rigidity is not sufficient, the bottle mounting portion is strong. And a bottle with a handle to which the bottle handle is attached.

In order to solve the above problems, the present invention provides a plastic bottle handle that is fitted and fixed to a handle mounting portion formed on a plastic bottle.
A vertical grip,
A flexible upper arm that protrudes from the upper end of the bottle-side surface of the grip portion and can be bent in the vertical direction;
A lower arm portion that is rigid and does not flex in the vertical direction, protruding from the lower end of the bottle-side surface of the grip portion;
The upper arm portion or the lower arm portion extends from the distal end portion toward the other arm portion, and when pushed out along the surface of the other arm portion, the upper arm portion is bent upward. The flexure that can be held so that the distance between the upper arm portion and the lower arm portion is not narrowed by moving while turning and fitting into the tip engaging groove formed in the tip portion of the other arm portion. A prevention plate,
An upper engagement protrusion protruding upward from a tip portion of the upper surface of the upper arm portion;
A lower engagement protrusion that protrudes downward from the tip of the lower surface of the lower arm,
It is characterized by having.

  Here, when the deflection preventing plate extends from the distal end portion of the lower arm portion toward the upper arm portion, the distal end engaging groove is formed at the distal end portion of the upper arm portion.

  In the bottle handle of the present invention, the lower arm portion located on the lower side of the bottle is a rigid arm portion that does not bend in the vertical direction of the bottle. Therefore, even when the shape accuracy of the lower end surface of the bottle-side handle attachment portion against which the lower surface of the rigid arm portion is pressed is poor, sufficient mechanical engagement between them can be ensured. Moreover, even when the out-of-plane rigidity of the lower end surface is low, sufficient mechanical engagement between them can be ensured. Therefore, it can be firmly fixed to the bottle as compared with the conventional bottle handle in which the lower arm portion is a flexible arm portion that can be bent up and down.

  Here, the said bending prevention board is equipped with the 1st reinforcement rib extended in the long side direction on the bottle side surface, It is characterized by the above-mentioned.

  Moreover, the said bending prevention board is equipped with the 2nd reinforcement rib extended in the long side direction on the surface on the opposite side to the bottle side surface.

  Furthermore, the lower arm portion is provided with a third reinforcing rib on the upper surface thereof from the bottle side surface of the grip portion to the second reinforcing rib.

  Since the reinforcing ribs are formed on the anti-bending plate in this way, the state where the upper and lower arm portions are reliably brought into contact with the upper and lower end surfaces of the handle mounting concave portion can be maintained. Thereby, the fixing strength of the handle can be increased.

  In particular, when reinforcing ribs are formed on each of the deflection preventing plate and the lower arm portion, it is possible to reliably prevent the handle from being detached due to an impact force acting when the bottle is dropped.

  Next, the present invention is characterized in that a positioning projection protruding from the upper end surface of the grip portion is provided.

On the other hand, the present invention includes a plastic bottle having a handle attachment portion formed on the outer peripheral surface portion of the body portion, and a plastic handle attached to the handle attachment portion after blow molding of the bottle. In the bottle
The handle mounting portion is
A recess having a predetermined width extending in the vertical direction of the bottle;

The lower arm is a rigid arm that does not substantially bend in the vertical direction of the bottle,
The upper arm is a flexible arm that can bend in the bottle vertical direction,
The upper arm portion is prevented from being bent by pushing the handle into the recess and pushing the tip portion of the anti-bending plate beyond the claw portion into the tip engagement groove, and the handle is attached to the handle attachment portion. It is characterized by being held in a fixed state.

  In the bottle with a handle of the present invention, the lower arm portion located on the lower side of the bottle of the handle is a rigid arm portion that does not bend in the bottle vertical direction. Therefore, even when the shape accuracy of the lower end surface of the bottle-side handle attachment portion against which the lower surface of the rigid arm portion is pressed is poor, sufficient mechanical engagement between them can be ensured. Moreover, even when the out-of-plane rigidity of the lower end surface is low, sufficient mechanical engagement between them can be ensured. Therefore, the handle can be firmly attached to the bottle as compared with the case of using a conventional bottle handle in which the lower arm portion is a flexible arm portion that can be bent up and down.

  Here, in this invention, the 1st reinforcement rib extended in an up-down direction is formed in the bottle side surface in the said bending prevention board, It is characterized by the above-mentioned.

  Moreover, the said bending prevention board is equipped with the 2nd reinforcement rib extended in the up-down direction on the surface on the opposite side to the bottle side surface.

  Furthermore, the lower arm portion is provided with a third reinforcing rib on the upper surface thereof from the bottle side surface of the grip portion to the second reinforcing rib.

  When the reinforcing ribs are formed on the anti-bending plate in this way, the state where the upper and lower arm portions are reliably brought into contact with the upper and lower end surfaces of the recess for attaching the handle can be maintained. Thereby, the fixing strength of the handle can be increased. In particular, when reinforcing ribs are formed on each of the deflection preventing plate and the lower arm portion, it is possible to reliably prevent the handle from being detached due to an impact force acting when the bottle is dropped.

  Next, in the present invention, the rib groove extending in the vertical direction in which the first reinforcing rib is fitted to the bottom surface of the recess extending from the end of the upper end surface on the bottle center side to the end of the lower end surface on the bottle center side. It is characterized by being formed.

  The bottom surface of the recess is formed with a vertically long shallow recess extending in the vertical direction for fitting the deflection preventing plate, the tip portion of the upper arm portion, and the tip portion of the lower arm portion. Yes.

  Further, the handle mounting portion includes an insertion groove formed in an opening edge portion of the upper end surface of the recess, and the handle is formed on the upper abutting surface of the handle facing the insertion groove. It is characterized by comprising positioning protrusions that are formed in a part and inserted into the insertion groove.

  By forming the rib groove into which the rib fits, the concave portion into which the anti-bending plate or the like fits, and the insertion groove into which the positioning protrusion fits, the handle can be positioned at a predetermined position and can be reliably prevented from shaking from side to side. .

  On the other hand, in the present invention, the initial shape of the anti-bending plate is a shape curved so as to protrude toward the bottle along the long side direction, the handle is pushed into the concave portion, and the tip of the anti-bending plate In a state in which the portion is fitted in the tip engagement groove, the bending prevention plate is closely attached to the bottom surface portion of the recess and is held substantially linearly.

  By holding the bending prevention plate that spreads the upper arm portion and the lower arm portion in a straight line, the vertical rigidity of the bending prevention plate can be secured. As a result, the strength of fixing the handle to the recess can be increased.

  In the present invention, the lower arm portion of the bottle handle is a rigid arm portion that does not bend in the vertical direction, and the upper arm portion located on the upper side is a flexible arm portion that can be bent in the vertical direction. The bending of the arm portion is blocked by a bending prevention plate. Therefore, when the shape accuracy of the lower end surface of the bottle handle attachment concave portion is poor, even when the rigidity is low, the handle fixing strength can be sufficient.

(Grip assembly procedure)
FIG. 3 shows a procedure for assembling the handle 10 to the bottle body 2. As shown in FIG. 3A, in the handle 10 before mounting, the tip 14 a of the anti-bending plate 14 is positioned closer to the grip portion 11 than the claw portion 17 of the upper arm portion 12. The tip end 14 a has an arcuate inner surface and can easily ride on the claw portion 17.

  First, as shown in FIG. 3A, the handle 10 is inclined forward by a predetermined angle with respect to the state attached to the bottle body 2, and the upper contact surface 12 a of the upper arm portion 12 is set to the bottle body 2. Is pressed against the upper end surface 7 of the recess 5 for attaching the handle, and the projection 15 is inserted into the insertion groove 7b, and the upper projection 16 is positioned in the upper fitting groove 7a.

  In this state, the lower portion of the grip portion 11 of the handle 10 is forcibly pushed toward the handle mounting recess 5. As a result, the lower arm portion of the handle 10 is bent by the tip end side of the portion of the upper arm portion 12 where the tip 14a of the bend preventing plate 14 is in contact, and the lower end surface 8 of the bottle body side is bent. 13 lower projections 18 can be pushed into the lower fitting grooves 8a.

  The solid line in FIG. 3B shows this state. After this, the deflection preventing plate 14 is forcibly pushed into the bottle center side. The tip 14a of the bending prevention plate 14 gets over the claw portion 17 while forcibly bending the upper arm 12 upward. When getting over the claw portion 17, the tip end 14a fits in the tip end engaging groove 12b, and the upper arm portion 12 returns to the lower side again. As a result, as shown by an imaginary line in FIG. 3B, the bending prevention plate 14 is engaged with the upper arm portion 12 without being detached, so that an assembled state of the handle 10 is formed. .

  The lower arm portion 13 is a rigid arm portion, and the flexible upper arm portion 12 is prevented from being bent by the deflection preventing plate 14. Therefore, the upper projection 16 of the upper arm portion 12 and the lower projection 18 of the lower arm portion 13 are held in the upper fitting groove 7a and the lower fitting groove 8a, respectively. Since the grip 10 is held in the groove 7 b, the handle 10 is fixed to the bottle body 2.

  In the above-described handle 10, the upper protrusion 17 and the lower protrusion 18 are formed at the tip portions of the upper arm portion 11 and the lower arm portion 13, respectively, and these are formed into the upper fitting groove 7 a of the handle mounting recess 5 and The handle 10 is fixed to the bottle side by fitting in the lower fitting groove 8a. Between the handle 10 and the recess 5, the upper contact surface of the upper arm portion 11 and the lower contact surface of the lower arm portion 12 are respectively an upper end surface 7 and a lower end surface on the handle mounting recess 5 side. If a mechanical engagement is formed so as not to come out of the protrusion 8, the protrusion and the groove can have various shapes and sizes.

(Another example of a handle)
FIG. 4 and FIG. 5 show another example of a handle that can be attached to the recess 5 for attaching the handle. 4 (a) is a side view of the handle before being attached to the bottle, FIG. 4 (b) is a detailed view of the A part thereof, and FIG. It is. 5 (a) is a side view showing the handle when the bottle is mounted, FIG. 5 (b) is an end view when viewed from the bottle side (direction of arrow D), and FIG. 5 (c) is B- It is sectional drawing of the part cut | disconnected by the B line.

  Referring to these drawings, the handle 100 of this example is a plastic bottle handle that is fitted into and fixed to a handle mounting recess 5 formed in the bottle body 2, and has a vertically long grip portion 111. And a flexible upper arm portion 112 that protrudes from the upper end portion of the bottle-side surface of the grip portion 111 and that protrudes from the lower end portion of the bottle-side surface of the grip portion 111. It has a rigid lower arm 113 that does not flex in the direction. Moreover, it extends toward the upper arm portion 102 from the distal end portion of the lower arm portion 113, and is pushed upward along the lower surface of the upper arm portion 112 while bending the upper arm portion 112 upward. An anti-bending plate that can move and fit into a tip engagement groove 112b formed at the tip of the upper arm portion 112, and can hold the space between the upper arm portion 112 and the lower arm portion 113 in an expanded state. 114. An upper engaging protrusion 116 protruding upward is formed at the tip of the upper surface of the upper arm 112, and a lower engagement protruding downward at the tip of the lower surface of the lower arm 113. A protrusion 118 is formed. The bending prevention plate 114 may be formed so as to extend from the distal end of the upper arm portion 112 to the lower arm portion 113, and a distal end engaging groove may be formed at the distal end of the lower arm portion 113.

  The shape of each part will be described in detail. The grip portion 111 includes a vertically long arc-shaped outer plate portion 111a having a constant width and thickness, and an arc-shaped inner plate portion 111b having a smaller width and a constant thickness. The shape is connected by the vertical ribs 111c. The upper end of the outer plate portion 111a is bent at an acute angle inward, and the upper end of the inner plate portion 111b is bent inward in an arc shape, and these are joined together and are continuous with the upper arm portion 112 having a constant thickness.

  The upper abutment surface 112a, which is the upper surface of the upper arm portion 112, is a curved surface that is slightly curved downward, and an upper protrusion 116 that protrudes upward with a constant width and constant thickness is integrally formed at the distal end portion thereof. Is formed. The upper protrusion 116 can be fitted into the upper fitting groove 7a of the upper end surface 7 on the bottle side from below.

  The lower surface of the upper arm portion 112 is a curved surface 112c slightly curved downward toward the distal end side, and a wedge-shaped claw portion 117 is formed at a portion on the distal end side. A tip engagement groove 112 b is formed by the end surface 117 a of the claw portion 117 and the lower surface tip portion of the upper arm portion 112. In this tip engagement groove 112b, the upper end 114a of the anti-bending plate 114 can be fitted over the claw portion 117.

  Next, the lower end of the outer plate portion 111 a of the grip portion 111 is bent inward at an angle smaller than 90 degrees and is continuous with the lower plate portion 113 a of the lower arm portion 113. The lower end of the inner plate portion 111b also bends inward in an arc shape and continues to the upper plate portion 113b of the lower arm portion 113. The lower arm portion 113 has a chevron shape in which the upper plate portion 113a and the lower plate portion 113b merge at the front end on the bottle center side, and these are connected by a triangular vertical rib 113c. Therefore, it is a rigid arm portion that has high rigidity in the vertical direction and does not bend in the vertical direction.

  The lower contact surface 113d, which is the lower surface of the lower arm portion 113, is an inclined surface that is inclined upward as a whole, and a lower protrusion 118 that protrudes downward with a certain width is integrally formed at the tip end portion thereof. This can be fitted into the lower fitting groove 8a of the lower end surface 8 on the bottle side from the upper side.

  The tip of the lower arm portion 113 having this configuration is curved in an arc shape at a substantially right angle and continues to the deflection preventing plate 114. The deflection preventing plate 114 is a vertically long rectangular plate having a constant width and a constant thickness, and a first reinforcing rib 114b having a substantially rectangular cross section extending in the vertical direction is formed at the center of the surface on the bottle side. The deflection preventing plate 114 can be mounted in the bottle-side concave groove 6a, and the first reinforcing rib 114b can also be fitted into the rib groove 6b formed in the concave groove 6a.

  Here, the bending prevention plate 114 of the handle 100 of the present example has a second reinforcing rib 114c formed on the surface opposite to the surface on the bottle side. The second reinforcing rib 114c is a rib having a substantially semicircular cross section that extends in the vertical direction at the center in the width direction of the deflection preventing plate 114. A third reinforcing rib 113e is also formed on the upper surface of the lower arm 113 at the center in the width direction. The third reinforcing rib 113e is a rib having a substantially rectangular cross section, and extends from the lower end portion of the second reinforcing rib 114c to the lower end portion of the inner plate portion 111b of the grip portion 111.

  The handle 100 having this configuration can be assembled to the bottle body 2 by the same assembling procedure as the handle 10 described above. That is, as shown in FIG. 4, in the handle 100 before attachment, the distal end 114 a of the bending prevention plate 114 is positioned closer to the grip portion 111 than the claw portion 117 of the upper arm portion 112. The initial shape of the deflection preventing plate 114 is a curved shape that is slightly convex toward the bottle side along the long side direction.

  The upper arm 112 of the handle 100 is pressed against the upper end surface 7 of the handle mounting recess 5 of the bottle body 2 to form a state in which the upper protrusion 116 is positioned in the upper fitting groove 7a. In this state, the lower portion of the grip portion 111 of the handle 100 is forcibly pushed toward the handle mounting recess 5. As a result, the lower arm portion of the handle 100 is bent by the lower end surface 8 of the upper arm portion 112 being bent downward and the lower end surface 8 of the bottle body side being bent. The lower projection 118 of 113 can be pushed into the lower fitting groove 8a.

  After this, the deflection preventing plate 114 is forcibly pushed into the bottle center side. The tip 114a of the anti-bending plate 114 slides along the guiding curved surface 112c of the upper arm portion 112 and gets over the claw portion 117 while forcibly bending the upper arm portion 112 upward. When getting over the claw portion 117, the tip end 114a fits into the tip end engaging groove 112b, and the upper arm portion 112 returns to the lower side again. As a result, as shown in FIG. 5, the bending prevention plate 114 is engaged with the upper arm portion 112 without being detached, and the assembled state of the handle 100 is formed.

  The lower arm portion 113 is a rigid arm portion, and the flexible upper arm portion 112 is prevented from being bent by the deflection preventing plate 114. Therefore, the upper projection 116 of the upper arm portion 112 and the lower projection 118 of the lower arm portion 113 are held in a state of being fitted in the upper fitting groove 7a and the lower fitting groove 8a, respectively. Therefore, the handle 100 is fixed to the bottle body 2.

  Moreover, the 1st-3rd reinforcement rib is formed, and the rigidity of the bending prevention board 114 and the lower arm part 113 is improved by these. Therefore, even when an impact force is applied to the bottle and the handle, such as when the bottle is dropped, there is a problem that the bending prevention plate 114 is detached and the handle 100 is detached from the bottle body 2. Absent.

  Furthermore, since the rib groove 6b into which the first reinforcing rib 114b fits and the recess 6a into which the bending prevention plate 114 fits are formed, the handle 100 is surely positioned at a predetermined position without rattling.

  Further, the initial shape of the anti-bending plate 114 is a shape that is curved so as to protrude toward the bottle along the long side direction. The handle 100 is pushed into the concave portion 5 and the tip of the anti-bending plate 114 is moved to the tip. In the state of being fitted into the engagement groove 112b, the bending prevention plate 114 is held in a substantially linear shape in close contact with the flat bottom surface portion of the recess. By holding the deflection preventing plate 114 supporting the upper arm portion 112 in a straight line, the rigidity in the vertical direction of the deflection preventing plate 114 can be secured. As a result, the fixing strength of the handle 100 with respect to the recess 5 can be increased.
